tilted preparatory to positioning it in the The sofa bed has a frameconsisting of two arms 1 connected together by means of a plurality oftransverse members 2 and toe board 2a. A mattress supporting or foldableframe 3 is mounted in the sofa frame, one end thereof being pivotallysupported on a pair of brackets 4 secured to arms 1.

The mattress supporting or foldable frame 3 comprises a plurality ofpivoted frame sections having side and end frame'bars and arranged to berectangular in shape for supporting a mattress when in unfoldedposition. The frame has a pair of arms 5 having a right angle bend ineach arm so that a long sub-arm thereof forms part of the mattress frame3, the short sub-arm thereof being pivoted to brackets 4. One end ofapair of side bars 6 of an innermost frame section ispivoted to the endof the long sub-arm by means of pivots 7. The next frame sec tionincludes the side bars 9. A board supporting frame or bracket 8 is madeup of suitable structures comprising opposite end assemblies, eachhaving a pair of bars 10 secured to and extending at right angles tobars .9. Bar 11 of each end assembly is disposed parallel to bar 9 andis connected to bars 10 at the outer ends thereof. A board 12 issuitably secured to the structures 8'so that it is alignable with andrests on the toe board 2a of the sofa frame. The board 12 is provided asa base for upholstery material so that the sofa will presenta uniformappearancewhen viewed from the front. An angle bar or rigid member 13 isconnected between the end assemblies for frame .8 and has .a length.equal to the width across the front of frame 3. Braces are .provided inframe 8 between said structures and bar 13 for strengthening the frame3. The board supporting frame .8 is fixedly or non.- collapsibly securedon the side bars 9 of the intermediate mattress supporting framesection, and the bars 9 are connected to one end of each bar 6. by meansof pivot pins 14. Another pair of bars 15, forming parts of an outermostframe section, has one end of each bar pivotally connected to theother-ends of bars 9 by means of pivot pins 16 (Fig. 8), the free endsof bars 15 beingconnected by means of a transverse angle bar 17 having alength equal to the width of frame 3. V The forward face of this angle.bar has a piece of wood 18 secured thereto. One leg of each of bars 9has a portion of the end thereof removed so thatthe other leg maythereof engage the adjoining ends of bars 6 and 15 for the purpose ofpreventing buckling of frame 3 when it is unfolded.

p The mattress frame 3 is supported on foldable legs at spaced pointsthereon. One set of legs 19 has one end thereof pivoted to one end ofbars 6 by means of pins 20 disposed adjacent to pivot pins 14. Eachleg19 is folded into the plane of bars 6 by means of links 21 and .22. Oneend of link 21 is pivoted to each leg 19 by means .of a pin 23 at apoint adjacent pin 20, the other end of link 21 being pivoted to one endoflink 22 by means .of :pin 2 T e vother end of link 22 :is pivoted .toa right angle bracket 25 by means of a pin 26. An intermediate pivot 22is provided to connect the link 22 to the bar 6 to coordinate thefolding action of the frame 3 into and out of the sofa frame. Each ofthe brackets 25 is suitably securedto arms 1 and a reinforcingbar 27 isdisposed diagonally across the legs of brackets 25- and is secured tothe ends of said legs. A' counter balancing spring 28 has one endconnected to a link 29 pivoted to pin 24, the other end of the counterbalancing spring being connected to a link 30 pivoted to pin 31 securedto one end of one of the legs of bracket 25.

The unpivoted or free'ends of bars 15 are supported on L-shaped legs 32,one end of each leg being connected to plates 36 pivotally mounted onbrackets 33 by means of pins 34, the brackets being secured to bars 15.Another leg 35 is secured to each of the plates 36 for supporting theunpivoted or free ends of 'bars 15 when folded to the position shown inFigs. 1, 2 and4 to 7. One end of link 37 is pivoted to one end of bar 9by means of pins 49, and the other end of link 37 is pivotally securedto plates 36 by means of pins 50, the arrangement being such that whenbars 15 and the transverse angle bar 17 are pivoted about pins 16, theplate 36 will rotate about pins 34, thereby causing the legs 32 and 35to selectively support the unpivoted ends of bars 15.

A mattress supporting fabric 38 is suspended from arms 5, bars 6 and 15'secured to bars 15, transverse bar 17 and running perpendicular to theabove referred to innermost and outermost wires) are seen to stabilizethe set of front edge springs 43 for yielding movement with the framewire 44 about a radius or hinge axis which is in the outermost wire ofthe fabric 41. This outermost wire (Fig. 1) has its opposite endsconnected to the springs 40 which suspend the fabric 38, since the endsof this wire extend beyond the clips 46 on each of the next to lastsprings 43 at the ends of the front edge. The layer of. fabric 41 hassome swinging action from its innermost wire at clips 52, but because ofthe underlying fabric 38, the fabric 41 is restricted so that theyielding front edge springs 43 and frame wire 44 actually hinge aboutfrom a second transverse bar 39 (Fig. 7) connected be- 15 by means ofsprings '42. One side of the fabric 41 is secured to a yieldable supportmade up of a plurality of conical upholstery coil springs 43 supportedon transverse bar 13 of the upholstery board supporting frame 8. A heavyWire 44 is positioned along the forward edge of springs 43 and theunsupported edges of springs 43 are connected to wire 44 by'means ofclips 45. The ends of wire 44 (Fig. l) encircle the end springs 43 andare then inturned to be connected to the outermost springs that suspendthe fabric 38 from the bars of the foldable frame. This connection withsprings 40 is effected by loosely inserting the inturned end of wire 44into the corner support for the sofa cushions when the mattresssupporting frame is folded into the sofa, thereby eliminating thenon-yieldable corner or edge that characterizes the prior art. Theresiliency is further attained by the movement of the frame wire 44turning within the helical springs 40 to which end wire 41 is connected.Accordingly, a flexible frame for the springs 43 is composed of theheavy wire 44 and the wire 41' of the fabric, both of which extendacross the front edge of the structure.

Referring to Figs. 1 and 14, the above structure is seen to include twolayers (Fig. 14) of the flexible link fabric in the seat section 15. Theupper layer of fabric 41 has its innermost longitudinal wire connectedby clip means 52 to the last wire of the underlying layer of fabric 38.The outermost longitudinal 'wire of the fabric 41 is directly connectedto the conical springs 43 by clips 46. The transverse wires of thefabric layer 41 (those W l the axis of the outermost wire of this fabric41 which is connected to the springs 43 by clips 46.

Assuming that the mattress supporting frame is in the extended positionshown in Fig. 3, the transverse bar 17 is grasped and rotated about pins16 to the Fig. 4 position. This will bring the cushion supporting fabric41 to the top and, as bars 15 are rotated about pins 16, the leg members32 and 35 will rotate about pins 34, placing leg 32 in alignment withbars 15 and causing legs 35 to support the unpivoted or free ends ofbars 15. Brackets 47 secured to bars 6, support legs 35, therebyproviding a rigid base on which legs 35 may rest for supporting theunpivoted ends of bars 15.

The board supporting frame is next grasped and lifted upwardly andsomewhat rearwardly so that legs 19 may be moved to a position inalignment with bars 6. The links 21 and 22 move pivot pins 22', 23, 24and 26 and will cause legs 19 to be rotated to the position shown inFigs. 5 to 7 and simultaneously stretch springs 28. As soon as themattress supporting frame has reached the position shown in'Fig. 5, thepivot pins 23 and 24 will be positioned to the right of pivot pin 26,thereby enabling the board supporting frame 8 to drop downwardly whilearms 5 are pivoted on brackets 4 and align the board 12 with the toeboard 2a. When the mattress supporting frame has been moved into theposition shown in Fig. 6, the cushion fabric 41 will be in its permanentposition for receiving the sofa cushions. For the purpose of preventingany possible movement of bracket-s 25, they are reinforced by angle bars48 secured to the leg of each bracket, thereby providing additionalsupport for the sofa bed.

' From the foregoing it will be observed that a simplified foldable legsupport for the unpivoted or free ends of bars 15 has been provided inboth the extended and folded condition'of the frame. The moving parts ofthe mattress frame have been reduced in number, thus clearing themattress so that the rubbing and pinching thereof which characterizesprior art constructions, has been eliminated. All pivoted supports areplaced outside of the mattress supporting frame so that the pivotedlegs, in either the unfolded or folded condition, are parallel to thebars 6 and 15 or at right angles thereto, depending upon the folded orunfolded condition of the mattress frame.
